Description
ществл етс переход от непрерывного режима питапи к импульсному. Скважность радиоимпульсов в цепп датчика Холла определ етс параметрами управл ющего генератора пр моугольных импульсов. С выхода датчика Холла через фильтр нижних частот импульсы поступают на видеоусилитель и далее - на пиковый детектор, выполненный на магнитоуправл емом ключе, врем срабатывани которого управл етс генератором пр моугольных импульсов. После детектировани информаци поступает на индикатор.There is a transition from continuous mode to pulse mode. The durability of the radio pulses in the Hall sensor circuit is determined by the parameters of the control generator of rectangular pulses. From the output of the Hall sensor through a low-pass filter, the pulses go to a video amplifier and then to a peak detector made on a magnetically controlled key, the response time of which is controlled by a square pulse generator. After detection, the information enters the indicator.
Включение в цепи управлени датчика Холла, магнитоуправл емого переключател позвол ет значительно повысить чувствительность и помехозащищенность демодул тора.The inclusion of a magnetically controlled switch in the control circuit of the Hall sensor allows a significant increase in the sensitivity and noise immunity of the demodulator.
